Details
We are going to upgrade the 2 routers "core" here in Roubaix in order to add capacity.

These chassis are now full in terms of linecard 8x10G. . We are going to switch to the new RSP 440 which will allow us to replace some of the line cards for the new 24x10G. The procedure is as follows :

- upgrade software
- replacement of the RSPs (stopping/ complete rerestarting of the necessary chassis)
-replacement of 2 of the linecards 8G by 24g

These intervention will take place during the night. We will start this night (from 10 to 11 ) with rbx-g1-a9 at 00:00 CET. No impact on the trafic is anticipated because we are going to force the trafic by rbx-g2 during the workings.

***** UPGRADE WARNING MESSAGE: *****
* This upgrade operation has a maximum timout of 90 minutes. *
* If you are executing the cmd for one specific location and *
* card in that location reloads or goes down for some reason *
* you can press CTRL-C to get back the RP's prompt. *
* If you are executing the cmd for _all_ locations and a node *
* reloads or is down please allow other nodes to finish the *
* upgrade process before pressing CTRL-C. *

% RELOAD REMINDER:
- The upgrade operation of the target module will not interrupt its normal
operation. However, for the changes to take effect, the target module
will need to be manually reloaded after the upgrade operation. This can
be accomplished with the use of "hw-module <target> reload" command.
- If automatic reload operation is desired after the upgrade, please use
the "reload" option at the end of the upgrade command.
- The output of "show hw-module fpd location" command will not display
correct version information after the upgrade if the target module is
not reloaded.
NOTE: Chassis CLI will not be accessible while upgrade is in progress.
Continue? [confirm]
This can take some time for a full chassis.
Ensure that system is not power cycled during the upgrades.
Please consult the documentation for more information.
Continue ? [no]: yes

FPD upgrade in progress on some hardware, reload/configuration change
on those is not recommended as it might cause HW programming failure
and result in RMA of the hardware.

The router has correctly started on the new images. We are updating the fpd:
FPD upgrade in progress. Max timeout remaining 89 min.

The upgarde of FPDs is done. We are rebooting a last time on all the nodes.

Comment by OVH - Thursday, 12 January 2012, 21:31PM

The router is updated and is stable. We reactive the trafic on it.

Comment by OVH - Thursday, 12 January 2012, 21:31PM

The trafic is reactivated. The 2 routers rbx-g1 ad g2 are working normally.

We will get back to work tonight since 00:00 CET.
The two routers are now updated in soft and we installed the new IOS XR on the new 440 RSPS. We will insert them tonight in the chassis rbx-g1 and g2.
If everything goes well, we can insert new 24x10G.

Our optics are well recognized by the cards but do not emit light. We suspect there is an incompatibility.

Comment by OVH - Tuesday, 17 January 2012, 04:13AM

We fallback on 8x10G.We will work with Cisco to fix the optics compatibility problem and check the exact implications of the message "MIXED_MEMORY_ALARM" back from the card while inserting.

Comment by OVH - Tuesday, 17 January 2012, 04:15AM

We could finally run another kind of optics.We'll let this 24x10G run in order to check its operating. If there is no more inconveniences, we will insert the next.

We are going to upgrade the capa between rbx-g1/g2-a9 and rbx-g1/g2-n7. The upgrade on the whole g2 is in progress. On g1, we are going to replace some 8T cards by 24x10G cards. We are going to do this operation tonight starting from 00:00 CET.

Comment by OVH - Friday, 27 January 2012, 01:40AM

We started the intervention in order to replace the cards 8x10G by 24x10G.
We will intervene first on rbx-g2-a9 then rbx-g1-a9.
